Application .led April 18, 1914. Serial No. 832,742.

To all 107mm t may concern Be it known that I, MARTIN RAsMUssEN, asubject of the King of Denmark, but ha ving filed my intention to becomea citizen of the United States, and resident of Racine, in the county ofRacine and State of Wisconsin, have invented certain new and usefullmprovements in Tanks; and I do hereby declare that the following is afull, clear, and exact description thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specification, as a combined filler-head and liquid-gage of a tank,its main object being to facilitate accessA to the tank and to utilizethe chart and pointer. casing of the gage as means for holding theclosure-cap of the filler-head in place, said invention being especiallydesigned for a hydrocarbon fuel-tank of a motor-vehiclelFigure l 0f thedrawings represents a filler-head and liquid-gage in aecordance with myinvention in connection with a fragment of a tank, the plane of thesection being indicated by line 1-1 in Figs. 2 and '3; Fig. 2, a planview of said head and gage partly in section, the gage being swung outof its normal position to the left; Fig. 3, a horizontal sectionindicated by line 3-3 in Fig. l, and Fig. 4, an elevation of a fragmentof the chart and pointer casing of the ga e having a bayonet-joint slot.

eferring by numerals to the drawings, 5 indicates a fragment of a tank,6 a bushing applied thereto and 7 a filler-head screwthreaded in thebushing. An opening in the filler-head is provided with an inner flange8 that constitutes a seat for a cap 9 in the form of a flat plate thatis substituted for' the screw-cap of common knowledge. Fastened at oneend by a rivet or otherwise to the top of the cap 9 is a semi-ellipticspringplate l0 having a center knob 11 that therewith constitutes alatch for engagement with a central cavity in the underside of the chartand pointer casing 12 of a gage, by which.

to determine the 'liquid contents of the tank. The casing 12 is pivotalon the upper shouldered end of a recessed plug 13 that is screw threadedin another opening in the llerhead. Screw-threaded in the plug 13 is theupper end of a longitudinally slotted'tube 14, and within the tube isaspiral strip` 15 sectional elevation of a combined' reduced at itsextremities to form pivots that turn in said plug 13 and a bearing 15provided in the lower end of said tube. Fast on the upper pivot of thespiral-strip l5 is a pointer 16, and this pointer traverses ameasuring-chart 17 held in said casing by a ring 18. The casing ispreferably glazed, the glass 19 being set in upon a gasket 2O an'd heldin place by a flanged ring section 12 of said casing. The ring sectionof the casing is preferably in bayonet-joint union with the remainder ofsaid casing to facilitate its removal. Guided on the depending tube 14is a float 21 and attached to the float is an angular spring-arm 22having a notched end that extends through the slot of said tube andslides upon the spiral strip l5, whereby said strip is turned to actuatethe pointer 16. The extent is predetermined by the length of the slot inthe tube 14 through which the spring-arm 22 of said iioat extends. Todetach the float its spring-arm 22 is withdrawn from the slot in thetube 14.

From the foregoing it will be understood that .the gage may be readilyassembled in connection with the filler-cap and as readily taken apart.

The casing part of the position shown by full lines in Fig. 1, thespring l0 is contracted and the closure cap 9 for the opening in thefiller-head held tight on its seat covered from dust and moisture. Toobtain access to the tank, it is only necessary to swing the pivotalcasing of the of the rise and fall of the ioatV gage being in the.

filler-head opening, this being a simple and easyoperation that may bethe aid of a tool.

I claim:

1. The combination of a ller-head of a tank having an opening therein, aremovable cap for which the opening in the head is provided with a seat,and a liquid gage having a chart and pointer casing thereof in pivotalconnection with said head and normally positioned over said cap.

2. The combination of a filler-head of a tank having an opening therein,a removable cap for which the opening in the head is provided with aseat, a spring latch on the cap, and a liquid gage having a chart andquickly performed without pointer easing thereof in pivotal connectionwith said head and normally positioned over the tube slot and notched toengage the spiral-strip, the extent of play of the float beingpredetermined by the length of said slot, a pointer on the upper end ofthe pivotend of said strip, and a measuring-chart'stationary in saidcasing opposite the pointer.

4. The combination of a filler-head of a tank having an opening therein,a removable cap for Which-the opening in thel head is provided with aseat, a plug 1n said head, a

separable glazed casing in pivotal connection with the plug and normallypositioned over said cap, a longitudinally slotted tube in detachabledepending connection with said plug, a spiral-strip having pivot endsthat turn in the plug and in a bearing provided in the tube, a floatguided on said tube, a spring arm on the float and extending through thetube slot and notched to engage the spiral-strip, extent of play of thefloat being predetermined by the length of said slot, a pointer fast onthe upper pivot end of said strip, and a measuring-chart stationary insaid casing opposite the pointer.

In testimony that I claim the foregoing I have hereunto set my hand atRacine in the county of Racine and State of Wisconsin in the presence oftwo Witnesses.
